Abstract: This paper presents a feedback linearization control scheme with sliding mode controller (SMC) for enhancing performance of the induction motor drive. The feedback decoupling controller is designed in a stationary (α-β) reference frame with rotor flux and stator current components as state variables. Since the induction motor drive system is sensitive to parameter variation and load disturbances, a robust control strategy based on sliding mode is implemented. Initially feedback linearization technique is simulated with conventional PI controller. Then the proposed scheme comprising of a sliding mode flux controller and a sliding mode speed controller is simulated. Both control schemes are simulated in MATLAB environment. Simulation results demonstrates that performance of sliding mode based scheme is more robust than fixed gain P-I controller based scheme.
